Just the Two of Us

This is the story of GeoVelo, the Missouri Humanities Council, and both the state and national Trail of Tears Association’s collaboration on a variety of geospatial projects. The most significant of these projects has been the Trail of Tears mapping project. The dates used in this timeline are generally when GeoVelo was first informed of the particular subproject. Any errors belong to Chris Dunn and GeoVelo.

Funding for the ToT

Funding for the ToT
MHC agrees to fund $24,000 for Trail of Tears research in three areas in Missouri.  “These projects will yield research documents which will be used for interpretive materials including signage, rack cards, news stories, digital media, and other materials to enhance cultural and historic tourism.  This research will ultimately provide the basis for updates to the NPS Trail of Tears National Historic Trail map for Missouri.” – Bill Ambrose

We Meet At Last

We Meet At Last

August 2017 Dr. Bill Ambrose requested help from the UM Extension Geographic Specialist to georeference an old road map. Dr. Shannon White, Ph.D. said, “We aren’t allowed to do that for you, but I know a guy who can.”

Trail of Tears GIS Starts

Trail of Tears GIS Starts

The Trail of Tears GIS has grown from a simple route map to one of the most complex GIS’s assembled by GeoVelo.  The GIS uses 14 different geodatabases and has upwards of 400 layers. – CD

Adding Precision

Adding Precision

GeoVelo began transcribing the 97 mile road survey calls into MS Excel. This was the first time this type of effort had been made in Missouri on any Trail of Tears route.

Kiosk Repair

Kiosk Repair

MHC had two older model free standing kiosks. The Executive Director asked if I could make them work. One was salvageable, repaired, and then reprogrammed. The other was recycled. The working kiosk is now in the Saint James office. – CD

Ground Control Markers

Ground Control Markers

The University of Missouri drone journalism program knew how to fly drones and take aerial imagery. But they were not adept at geospatially registering the images they took. This required the development of ground control markers for the flights at the Weldon Springs German Heritage area. GeoVelo developed a set of do-it-yourself ground control markers and published a blog article on the topic after they were such a success. Years later I still get comments about how well designed enterable these ground control markers are. Blog Article – CD

Article: Rediscovering the Trail of Tears

Article: Rediscovering the Trail of Tears

Our entire way of life today was touched by how we mapped most of the nation’s land west of the Appalachians. During the Antebellum period, the United States launched its most ambitious national program since the Revolution: The Public Land Survey System (PLSS), which employed thousands of rough men working in small teams under harsh conditions. The PLSS organized the western expanse into townships of…. CD  Read it Here

Magnetic Rocks

Magnetic Rocks

GeoVelo noticed the survey bearings on the 97 mile road plat were often in error and so began looking for potential sources of that error. Geological ground based magnetic deflection was identified as a possible cause.  In addition, the survey practices at the time did not always include recording the earth local magnetic variance from True North. So GeoVelo began to work on the magnetic declination issue when transcribing the calls on the 97 mile road plat.

It’s all µTeslas these days…

GeoVelo began experiments on micro Tesla field strength and historic Missouri magnetic anomalies. The geology and magnetic field strengths recorded and mapped by the Missouri Geological Survey and the USGS corresponded nicely with the errors in the 97 mile road plat.

German Heritage

German Heritage

Located near Weldon Springs, Missouri, the German Heritage Project involved discovering the old town of Hamburg just north of the Katy Trail. GeoVelo supported this effort by working with the Mizzou Drone Journalism team. GeoVelo integrated their data into a specific GIS created just for the German Heritage Project. Plus, GeoVelo and Archaeologist Erin Whitson rescued the University of Missouri’s expensive drone when it crashed. – CD
